Component Exaggeration

  We cannot exaggerate individual facial components using the in-betweeners. We therefore define rules to exaggerate the shape of a single facial component.These rules mostly involve scaling and rotation with magnitudes determined by comparing the component shapes of the given face with those of average face.

Facial Shape

  We divide the shape of the head into two rectangles. The first rectangle includes the upper part,above the eyes, and the second includes the lower part,below the eyes.These rectangles are sub-divided into left and right parts by a vertical line from the peak of the head. Figure 3(b-2) shows these rectangle with dashed lines. The degree of haggardness or roundness of the face can be estimated using the distance between the line connecting from p 1 to p 2 (in Figure 3(b-2)) and the mean of all the points in the left jaw region. The exaggeration parameters can be extracted by comparing the degree of haggardness or roundness to that of the average face (Figure 3(b-1)). Then the original feature points (Figure 3(b-2)) are sheered to become exaggerated feature points (Figure 3(b-3)) using the proportion specified by the exaggeration parameters.
